Only the first sample in which the species was identified is included in the presented data.

All the isolated Staphylococcus aureus strains were non-MRSA.

No significant differences were found between the two groups.

Lp = patients treated with Lactobacillus plantarum 299; C = control patients treated with chlorhexidine.
